It seems like just when the story is getting good, or picks up the pace, the book ends and you have to move on to the next one. Again we are getting some answers, but even more questions. Who is the older brother? Why doesn't Amr know of him? If the twins are somewhat symbiotic, why didn't they realize it before despite the warped minds? If every time she was warped, why wasn't Amr warped as well? Those last two may just be plot holes though.
